CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY

The present application is related to and claims the benefit under 35 U.S.C. §119(a) to a Korean patent application filed in the Korean Intellectual Property Office on Jan. 31, 2012 and assigned Serial No. 10-2012-0009592, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to contents sharing in a network.

BACKGROUND OF THE INVENTION

As performances of mobile terminals and digital devices are improved recently, a demand for services for sharing contents between the mobile terminal and the digital device is gradually increasing. To share the contents, it is necessary to configure connection in a network between the smart phone and the digital device. For the contents sharing, the mobile terminal, as a control device, accesses the network, searches for other devices, and shares contents with the discovered devices.

The contents sharing can fail for various reasons. The contents sharing is infeasible, for example, when the mobile terminal does not access the network or when the mobile terminal accesses the network but does not discover other devices. When the contents sharing fails, a user can confirm the failure reason only through a separate identification process. For example, the user needs to additionally check the network connection state. Even when a plurality of devices is discovered, the user cannot recognize them immediately.

As discussed above, when the contents are shared over the network between the devices, the user cannot obtain detailed information of the contents sharing process. For this reason, it is necessary to provide a solution for increasing user convenience by providing the user with information regarding various states occurring in the contents sharing process.

SUMMARY OF THE INVENTION

To address the above-discussed deficiencies of the prior art, it is a primary aspect of the present invention to provide an apparatus and a method for providing user with information regarding various states occurring in a contents sharing process in a network.

Another aspect of the present invention is to provide an apparatus and a method for displaying network connection state in a contents sharing process in a network.

Yet another aspect of the present invention is to provide an apparatus and a method for displaying the number of devices discovered in a contents sharing process in a network.

Still another aspect of the present invention is to provide an apparatus and a method for displaying the number of available services in a contents sharing process in a network.

According to one aspect of the present invention, an operating method of a control device in a contents sharing network includes determining a current state of possible states in a contents sharing process over a network; and displaying an icon indicating the current state among a plurality of predefined icons. The states are defined as a combination of at least one item of network connection, device discovery, a type of the discovered device, the number of the discovered devices, and existence of an available additional service.

According to another aspect of the present invention, an apparatus of a control device in a contents sharing network includes a display unit; at least one processor; a memory; and one or more modules stored to the memory and executed by the at least one processor. The module determines a current state of possible states in a contents sharing process over a network, and comprises an instruction for displaying an icon indicating the current state among a plurality of predefined icons, and the states are defined as a combination of at least one item of network connection, device discovery, a type of the discovered device, the number of the discovered devices, and existence of an available additional service.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 through 8, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged network.

Exemplary embodiments of the present invention provide a technique for providing a user with information of various states occurring in a contents sharing process in a network.

FIG. 1 illustrates a contents sharing network according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the contents sharing network includes a sharing network 110, a control device 120, and player devices 130.

The sharing network 110 is a communication interface for exchanging data between the devices 120 and 130. The sharing network 110 can be wired or wireless. For example, the sharing network 110 can be configured based on a wireless Local Area Network (LAN). In this example, the sharing network 110 can include an Access Point (AP). For example, the sharing network 110 can be configured based on a communication standard such as Institute of Electrical and Electronics Engineers (IEEE) 802.3i, IEEE 802.3u, and IEEE 802.11a/b/g. The sharing network 110 can be referred to as a home network.

The control device 120 holds contents and controls the player devices 130. In detail, the control device 120 can output its stored contents through the player device 130. The control device 120 searches for the player device 130. For example, the control device 120 can be a mobile terminal such as mobile phone, smart phone, laptop computer, or tablet Personal Computer (PC).

The player device 130 plays the contents under the control of the control device 120. For example, the player device 130 can be an electronic product such as PC, television (TV), audio, camera, refrigerator, and vacuum cleaner. The mobile terminal can function as the player device 130. For example, when the player device 130 includes a display means such as PC, TV, or camera, the player device 130 can display images or videos provided from the control device 120. When the player device 130 includes a sound output means such as PC, TV, or audio, the player device 130 can output sound data provided from the control device 120.

In the contents sharing network of FIG. 1, a user can play the contents stored to the control device 120 through the player device 130 by controlling the control device 120. In so doing, the control device 120 provides the user with information regarding various states occurring in the contents sharing process using a plurality of predefined icons. Hereafter, the present invention uses the term ‘icon’. The term ‘icon’ represents image-based mark to deliver information to the user through User Interface (UI) and can be replaced by a term ‘image’, ‘indicator’ or ‘notification’. For example, the icons are shown in FIGS. 2 through 5.

The control device 120 can determine whether there is an additional service provided together with the playing content, and inform of the number and the type of the available additional services. For example, the additional service can include information service of a person (e.g., a singer or a composer for music, and a director or an actor for movie) relating to the content, Internet Movie Data Base (IMDB) service (e.g., relevant images, movie synopsis, and review search), and advertisement service. More specifically, the control device 120 can obtain information of the additional service during the contents playback and show the additional service corresponding to the obtained information. For example, the additional service information can include a particular Uniform Resource Location (URL). Herein, the additional service information can be contained in contents data or transmitted from a server which streams the content. In this example, the additional service information can be transmitted to the control device 120 at a specific time (e.g., when a particular character appears in a movie) of the contents playback. Accordingly, the information of the number or the type of the additional services can be generated or extinguished during the contents playback.

FIGS. 2A and 2B illustrate icons indicating the network connection state in the contents sharing network according to an exemplary embodiment of the present invention. FIG. 2A depicts the icon informing that the control device is not connected to the network, and FIG. 2B depicts the icon informing that the control device is connected to the network.

In FIG. 2A, the icon indicating no network connection is represented using a figure. Alternatively, the icon indicating no network connection can be represented using a figure or a character different from FIG. 2 alone or in combination. In FIG. 2B, the icon indicating the network connection is represented using characters alone. Alternatively, the icon indicating the network connection can be represented using a character or a figure different from FIG. 2 alone or in combination.

FIGS. 3A to 3C illustrate icons indicating one device discovered in the contents sharing network according to an exemplary embodiment of the present invention. FIG. 3A depicts the icon informing that only the TV is discovered as the player device, FIG. 3B depicts the icon informing that only the PC is discovered as the player device, and FIG. 3A depicts the icon informing that only the laptop computer is discovered as the player device.

Referring to FIGS. 3A, 3B and 3C, the icon indicating the single device discovered includes a first mark 310 indicating the type of the single device discovered. In FIGS. 3A to 3C, the first mark 310 is represented using a figure or an image. In other exemplary embodiments of the present invention, the first mark 310 can be represented using a different figure or image from that illustrated FIGS. 3A to 3C or using the figure and the character alone or in combination. While the icons of FIGS. 3A to 3C include the mark of the mobile terminal in the left lower part, the mark of the mobile terminal can be replaced by a different shape or omitted.

FIGS. 4A and 4B illustrate icons indicating no device discovered or a plurality of devices discovered in the contents sharing network according to an exemplary embodiment of the present invention. FIG. 4A depicts the icon indicating no device discovered, and FIG. 4B depicts the icon indicating a plurality of devices discovered.

Referring to FIGS. 4A and 4B, the icon indicating no device discovered and the icon indicating the plurality of the devices discovered include a second mark 410 indicating the number of the discovered devices. In FIGS. 4A and 4B, the second mark 410 is represented in combination of the figure and the number. In other exemplary embodiments of the present invention, the second mark 410 can be represented in combination of the figure and the number different from FIGS. 4A and 4B, using the character or the number alone or in combination, or using the figure alone. While the icons of FIGS. 4A and 4B include the mark of the mobile terminal in the left lower part, the mark of the mobile terminal can be replaced by a different shape or omitted.

FIGS. 5A to 5E illustrates icons indicating existence of an available additional service in the contents sharing network according to an exemplary embodiment of the present invention. FIG. 5A depicts the icon indicating the available additional service when the control device is not connected to the network, FIG. 5B depicts the icon indicating the available additional service when the control device is connected to the network, FIG. 5C depicts the icon indicating the available additional service when the single device is discovered, FIG. 5D depicts the icon indicating the available additional service when a plurality of devices is discovered, and FIG. 5E depicts the icon indicating the available additional service when no device is discovered.

Referring to FIGS. 5A to 5E, the icons indicating the existence of the available additional service include a third mark 510 indicating the number of the available additional services. The third mark 510 can be displayed any time regardless of whether the network is connected, whether the device is discovered, and the number of the discovered devices as shown in FIGS. 5A to 5E. This is because the additional service relates to the playing content. Referring to FIGS. 5D and 5E, the second mark 410 and the third mark 510 indicating the number of the discovered devices are represented in similar shapes. The second mark 410 and the third mark 510 can be represented in different shapes for clear distinction. In FIGS. 5A to 5E, the third mark 510 is represented in combination of the figure and the number. In other exemplary embodiments of the present invention, the third mark 510 can be represented in combination of the figure and the number different from FIGS. 5A to 5E, using the character or the number alone or in combination, or using the figure alone.

When the plurality of the devices is searched and the plurality of the additional services is available as shown in FIG. 5D, the control device can provide the user with a list of the discovered devices and a list of the additional services. For example, the list of the devices and the list of the additional services can be formed as shown in FIG. 6. FIG. 6 depicts the device list and the service list in the contents sharing network according to an exemplary embodiment of the present invention. In FIGS. 5A to 5E, the device list 610 includes four devices and the service list 620 includes two additional services.

As stated above, the control device determines the current state of the possible states in the contents sharing process over the network and displays the icon indicating the current state among the plurality of the predefined icons. In so doing, the states are defined as the combination of at least one item of the network connection or disconnection, the device discovery, the type of the discovered device, the number of the discovered devices, and the presence of the available additional service. The predefined icons include at least one of the icon indicating no network connection, the icon indicating the network connection, the icon indicating no device discovered, the icon indicating the single device discovered, the icon indicating the multiple devices discovered, the icon indicating existence of the available additional service, and the icon indicating the number of the available additional services.

FIGS. 7A and 7B illustrate operations of the control device in the contents sharing network according to an exemplary embodiment of the present invention.

Referring to FIGS. 7A and 7B, the control device determines whether the control device is connected to the network in step 701. Whether the network is connected can be determined when an application supporting the contents sharing is executed. That is, to share the contents over the network, the control device initially determines whether the control device is connected to the network.

When the network is not connected, the control device displays the icon indicating no network connection in step 703. For example, the icon indicating no network connection is shown in FIG. 2A. In so doing, when there is the additional service provided together with the playing content, the icon indicating no network connection can include the mark indicating the existence of the additional service and the number of the additional services as shown in FIG. 5A.

In step 705, the control device determines whether a user's access command occurs. For example, when the network is configured based on the wireless LAN, the control device determines whether the user instructs to access a particular AP.

When the access command occurs, the control device displays the icon indicating the network connection and accesses the network in step 707. For example, the icon indicating the network connection is shown in FIG. 2B. At this time, when there is the additional service provided together with the playing content, the icon indicating the network connection can include the mark indicating the existence of the additional service and the number of the additional services as shown in FIG. 5B. Next, the control device returns to step 701.

When the network is connected in step 701, the control device searches for the device connected to the network in step 709. For example, the control device can search for other device by trying to receive a packet from the other device. Alternatively, the control device can search for other device by transmitting a packet requesting a response to the other device and checking whether the response is received. The device search can be performed periodically at regular time intervals during the network connection.

In step 711, the control device determines whether at least one device is discovered. For example, the control device determines whether a packet is received from other device or whether other device responds to the request of the control device.

When detecting no device, the control device displays the icon indicating no device discovered in step 713. For example, the icon indicating no device discovered is shown in FIG. 4A. In so doing, when there is the additional service provided together with the playing content, the icon indicating no device discovered can include the mark indicating the existence of the additional service and the number of the additional services as shown in FIG. 5E. Next, the control device goes back to step 709.

By contrast, when detecting at least one device, the control device determines whether the number of the discovered devices is one in step 715.

When the number of the discovered devices is one, the control device displays the icon indicating the single device discovered in step 717. The icon indicating the single device discovered includes the mark indicating the type of the discovered device. For example, the icon indicating the single device discovered is shown in FIGS. 3A, 3B, or 3C. In so doing, when there is the additional service provided together with the playing content, the icon indicating the single device discovered can include the mark indicating the existence of the additional service and the number of the additional services as shown in FIG. 5C.

In step 719, the control device determines whether the icon indicating the single device discovered is clicked. The click can be recognized through an input means such as touch screen, keypad, or touch pad.

When the icon indicating the single device discovered is clicked, the control device shares the playing contents with the one device discovered in step 721. In detail, the control device compares protocol and media format of the playing contents with protocol and media format supported by the discovered device. When the discovered device can play the content, the control device transmits data of the playing contents or information (e.g., Uniform Resource Identifier (URI)) required to play the content.

When the number of the discovered devices is two or more in step 715, the control device displays the icon indicating the multiple devices discovered in step 723. The icon indicating the multiple devices discovered includes the mark indicating the number of the discovered devices. For example, the icon indicating the multiple devices discovered is shown in FIG. 4B. In so doing, when there is the additional service provided together with the playing content, the icon indicating the multiple devices discovered can include the mark indicating the existence of the additional service and the number of the additional services as shown in FIG. 5D.

In step 725, the control device determines whether the icon indicating the multiple devices discovered is clicked. The click can be recognized through the input means such as touch screen, keypad, or touch pad.

When the icon indicating the multiple devices discovered is clicked, the control device displays the list of the discovered devices in step 727. At this time, when the available additional service exists and the icon indicating the multiple devices discovered includes the mark indicating the existence and the number of the additional services, the list of the additional services is displayed together as shown in FIG. 6.

In step 729, the control device determines whether one device is selected in the device list. The selection can be recognized through the input means such as touch screen, keypad, or touch pad.

When one device is selected, the control device shares the playing contents with the one device discovered in step 731. In detail, the control device compares the protocol and the media format of the playing contents with the protocol and the media format supported by the discovered device. When the discovered device can play the content, the control device transmits the data of the playing contents or the information (e.g., URI) required to play the content.

Although not illustrated in FIG. 7B, when the additional service list is displayed in step 727, the control device determines whether one additional service is selected. When one additional service is selected, the control device can execute the selected additional service. When the icon includes the mark indicating the existence of the additional service in steps 703, 705, 713 and 717, the control device can determine whether the icon is clicked. When the icon is clicked, the control device can display the additional service list. Next, the control device determines whether one additional service is selected. When one additional service is selected, the control device can execute the selected additional service.

The peripheral interface 823 connects input/output peripheral devices of the control device to the processor 822 and the memory 810 under the control of the memory controller 821. The control device can include a plurality of processors 822. Using various software programs, the processor 822 performs diverse functions for the control device, and processes and controls voice communication and data communication. In addition to those typical functions, the processor 822 executes a particular software module (instruction set) stored to the memory 810 and performs various functions corresponding to the particular module.

The processor 822, the peripheral interface 823, and the memory controller 821 can be embodied in a single chip. Herein, the single-chip construction is referred to as the processor unit 820. Notably, these components can be embodied as separate chips, rather than the single chip.

The communication unit 830 includes the RFIC unit 831 and the baseband processor 832. The RFIC unit 831 transmits and receives electromagnetic waves. The RFIC unit 831 converts a baseband signal output from the baseband processor 832 to the electromagnetic waves and transmits the electromagnetic waves over an antenna. The RFIC unit 831 converts and provides the electromagnetic waves received over the antenna, to the baseband processor 832. The RFIC unit 831 includes an RF transceiver, an amplifier, a tuner, an oscillator, a digital signal processor, a Coding-Decoding (CODEC) chip set, and a Subscriber Identity Module (SIM) card.

That is, the audio IC unit 850 provides an audio interface between the user and the control device with the speaker 860 and the microphone 870. The audio IC unit 850 receives a data signal from the peripheral interface 823 of the processor unit 820 and converts the received data signal to an electric signal. The converted electric signal is fed to the speaker 860, and the speaker 860 converts and outputs the electric signal to sound waves audible by the person. The microphone 816 converts sound waves received from the person or other sound sources to the electric signal. The audio IC unit 850 receives the converted electric signal. The audio IC unit 850 converts the received electric signal to an audio data signal and sends the converted audio data signal to the peripheral interface 823. The audio data is transmitted to the memory 820 or the communication unit 830 through the peripheral interface 823. The audio IC unit 850 can include a jack (not shown) for providing the interface to an attachable and detachable ear phone, head phone, or head set. The head set can allow both of the output (a single-earpiece or double-earpiece head phone) and the input (a microphone). The jack can be called an earphone jack or a headset jack.

The display unit 880 provides an output interface between the control device and the user. The input unit 890 provides an input interface between the control device and the user. When the display unit 880 is a touch screen, the display unit 880 and the input unit 890 can be constructed as a single block. In this example, the display unit 880 sends the user's touch input to the control device. The medium for showing the output of the control device to the user; that is, the display unit 880 shows the visual output to the user. The visual output is represented as text, graphics, video, or a combination of them. The user inputs through the display unit 880 using haptic contact, tactile contact, or a combination of them. The display unit 880 has a touch sensing face for receiving the user input. For example, a contact point between the display unit 880 and the user corresponds to a digit of a finger of the user contact. The user can contact the display unit 880 using an adequate object such as stylus pen. When the user inputs through the touch screen, the display unit 880 detects the contact by interworking with the relevant software module (instruction set). The detected contact is converted to an interaction corresponding to the user interface object (for example, a soft key) displayed on the display unit 880.

The display unit 880 can employ various display technologies. For example, the display unit 880 can use, but not limited to, Liquid Crystal Display (LCD) technology, Light Emitting Diode (LED) technology, Light emitting Polymer Display (LPD) technology, or Organic LED (OLED) technology. The display unit 880 can detect the start, the movement, and the halt or end of the contact using various touch detecting technologies such as capacitive detection, resistive detection, infrared detection or surface acoustic wave detection. For doing so, the display unit 880 can use proximity sensor array technology or other technologies for determining the contact point on the touch screen. The visual output is not represented, and a touch detection tablet for detecting only the touch input may be used.

Beside the touch screen, the control device can include a touch pad (not shown) for activating or deactivating a particular function. Unlike the touch screen, the touch pad sometimes detects only the touch input without displaying the visual output. The touch pad can have a separate touch sensing face detached from the display unit 880, or may be formed in an extension portion of the touch sensing face of the display unit 880.

The control device includes a power system (not shown) for supplying power to its components. The power system can include a power source (AC power source or battery), a power error detection circuit, a power converter, a power inverter, and a charging device or/and a power level display device (LED). Also, the power system can include a power management and control device for generating, managing, and distributing the power.

The control device can input and use various functions executable by inputting to the display unit 880, through a touch pad. Such functions can use a physical input/control device (e.g., a dial or buttons), which corresponds to a push button for turning on/off and locking the control device, a volume control rocker button, and a slider switch for ringer profile and toggling. The control device can have a function for processing voice input to activate or deactivate a preset function through the microphone 870.
